7D Question

Last Fall I purchased a 7D and two lenses. A 15-85mm, and 70-200 f/4. Also a 1.4 TC III. This is my first DSLR. Previously, starting in the 60's, I had Nikon SLRs which are now displayed as relics in one of my children's home. At that time I guess I was an advanced amateur. Then I dropped out for about fifteen years.

Now I'm back and a beginner. After considerable research I chose Canon, and to me the 7D is an awesome camera. I'm finding it to be a challenging, but fun, experience. I'm getting to the point where I am becoming familiar enough with the beast to get it to do my bidding without resorting to the manual. I love the 7D and AF and IS. Especially now that I'm getting a feel for the camera and lenses and turning out some images that I'm not ashamed of.

There are a lot of complaints and threads about the age of the 7d and Canon delaying the new and improved 7D, what ever they may call it.

Now to my question, Are the majority of 7D users actually butting up against the limits of the camera to a point where they need a better body? If so, I'm envious because I don't see myself ever reaching that point. So far, all the limiting factors have been me, not the 7D or the lenses.
